One of the conspicuous changes in kitchens is that kitchen space is more economically constructed than ever before giving more considerations to functionality. At the same time, eco-friendliness begins enjoying more attention for health and well-being reasons. Which is more important between functionality and eco-friendliness is a matter of personal taste and judgement. But eco-friendliness has become one of the more critical criteria for users to choose kitchen furniture. This paper examines the design trends of Contemporary kitchen furniture from the perspective of functionality and eco-friendliness. Results show that, as has been expected, many of kitchen furniture items manufactured by major furniture businesses have been found more functional and more eco-friendly than before the research period. I expect this trend to continue long into the future.

Urban design claiming the notion of 'Sustainability', which inevitably includes ecological complexity, is normally geared towards the reflection of environmentally-friendly technical guidelines in the existing planning process. Although physical planning should be combined with economic, social, cultural, environmental issues, and policies, it is conducted conventionally as the sum of the closed sectoral approaches of planning. To overcome this limit, Design Charrette was invented for sustainable urban design or community design, which should consider the complexity of diverse issues. This design process unveils complicated and divergent problems and a variety of stakeholders participate in the integrated design simultaneously and cooperatively. Because Design Charrette must also be a process of agreement, it is used for sustainable community design. The aim of this study was to introduce Design Charrette as an alternative of Korean sustainable urban design, which is regarded as 'making guidelines related to green principles'. For such a purposes, the definition and differentiation of Design Charrette will be explained with an analysis of the introduction background, benefit and procedure. The contents, system and process of Design Charrette will be analyzed through case studies in Canada, where this method of design is widespread. In the last part, the implementation system (the comprehensive system of organization / content and direction of planning / process and output) will be deduced after concentrated analysis of one respected case, 'Sensitive Urban Infill Charrette' of the City of Surrey. This implementation system will be a crucial reference to develop Korean Design Charrette.

In recent years, the development and market participation of major makers of next-generation eco-green vehicles has been accelerating. Consumer interest has also increased. Consumer characteristics, consumption type, characteristics of next-generation eco-friendly vehicles, and government policies on next eco-green vehicles. The results of this study are as follows. In Korea, there was no significant difference by gender, age, monthly average income, and consumer type. However, there was no significant difference in purchase intention by gender, age, and monthly income, Respectively. In the case of Japan, there was no significant difference by gender, age, monthly income, and consumer type. In Korea, on the other hand, images such as brand, color, and design have positive effects on eco-friendly vehicles. In the case of Japan, image and stability have a positive effect on consumers' purchasing behavior. Therefore, it is important for Japanese consumers to consider not only the image of purchasing an eco-friendly vehicles, but also the safety of the vehicles body, appear. In the case of Korea, the socio-environmental value-seeking type has a significant relationship with the purchasing intention. In the case of socio-environmental value-seeking type, the government's support policy such as carbon dioxide tax, direct support from the national or local governments, gasoline tax, Carbon tax and fuel related tax relief showed positive effects. In the case of Japan, the price-seeking type and the socio-environmental value-seeking type were found to have a significant relationship with the purchasing intention. Both the price-seeking type and the socio-environmental value-seeking type showed that the carbon dioxide tax, Direct support, gasoline tax, gasoline tax, and carbon tax, etc. have positive effects.

This study was intended to develop some lounge wear ensembles of emotional design by using an eco-friendly material, Kenaf fabrics in line with the contemporary trend of valuing health and environment. With market survey on commercially available indoor clothing ensembles in the market, the designs of lounge wear ensembles being on sale via on/off-line routes were analyzed. Provided by Korea High Tech Textile Research Institute, Kenaf fabrics were employed to make 4 pieces of lounge wear for women (cardigan, T-shirt, slacks, vest) and 4 ones for toddlers. In addition, some housewives in their thirties or forties who lived in Seoul were asked to respond to a series of questionnaires concerning the prototypes made directly in order to evaluate consumer satisfaction with them. Although the consumer awareness of Kenaf fabrics is very low as far, this attempt to present the designs of lounge wear made of Kenaf to young housewives who have a lot of concern for and purchase experiences of eco-friendly materials is meaningful in the light of the possibility to popularize Kenaf which is not familiar as a textile material yet.

Anomaly detection on building energy consumption has been regarded as an effective tool to reduce energy saving on building operation and maintenance. However, it requires energy model and FDD expert for quantitative model approach or large amount of training data for qualitative/history data approach. Both method needs additional time and labors. This study propose a machine learning and data science approach to define faulty conditions on hourly building energy consumption with reducing data amount and input requirement. It suggests an application of Support Vector Data Description (SVDD) method on training normal condition of hourly building energy consumption incorporated with hourly outdoor air temperature and time integer in a week, 168 data points and identifying hourly abnormal condition in the next day. The result shows the developed model has a better performance when the ${\nu}$ (probability of error in the training set) is 0.05 and ${\gamma}$ (radius of hyper plane) 0.2. The model accuracy to identify anomaly operation ranges from 70% (10% increase anomaly) to 95% (20% decrease anomaly) for daily total (24 hours) and from 80% (10% decrease anomaly) to 10%(15% increase anomaly) for occupied hours, respectively.
